Bionic bacteria may help make new drugs, biofuels: Artificially enhanced bacteria capable of producing new kinds of synthetic chemicals

Posted: 21 Sep 2011 02:28 PM PDT

A strain of genetically enhanced bacteria developed by researchers at the Salk Institute for Biological Studies may pave the way for new synthetic drugs and new ways of manufacturing medicines and biofuels, according to a new paper.

CSI: Microbial version without PCR

Posted: 21 Sep 2011 10:32 AM PDT

Researchers have developed PCR-free techniques for identifying the most active microbial populations in samples based on the PhyloChip, a high-density DNA microarray. These new techniques will be used in a wide variety of applications including the development of advanced biofuels.

Genetic 'GPS' system to comprehensively locate and track inhibitory nerve cells created

Posted: 21 Sep 2011 10:23 AM PDT

Neuroscientists have succeeded in creating what amounts to a GPS system for locating and tracking GABA inhibitory neurons, a vital class of brain cells that until now has eluded comprehensive identification, particularly in living animals. 20 mouse lines provide views of cortical GABA neurons not previously possible.

Researchers discover how 'promiscuous parasites' hijack host immune cells

Posted: 21 Sep 2011 09:00 AM PDT

Researchers recently discovered how T. gondii evades our defenses by hacking immune cells, making it the first known parasite to control its host's immune system. A new study describes a forced partnership between parasite and host that challenges common conceptions of how pathogens interact with the body.
